isa s eciiication.

This invention relates to improvements 1n the fastening' devicesby which a vestibulel curtain, which is attached to a spring roller fastened upon the door frame of one car, is

secured in osition on the door frame of the next car, W en pulled across the bellows and diaphragm which form the vestibule between the cars my object bein to rovide-a simple and effective device of t is c aracter, whereby the loop attached to the free end of the curtain may be readily securedin position when the cars are coupled together; and whereby the loop will be automatically released to prevent the rupture of the curtain, should the cars become separated, from an cause, before the curtain has been release I attain my object'bv constructing the fastener in'the Inanner illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation ofthe fastener; 2, a longitudinal section thereof; and Fig. 3, an end view with the latch lever shown sectioned on a line with the rear face of the bracket.

Like numerals designate like parts in the several views.

The fastener comprises a support or bracket 1, adapted to be rivet ,d or otherwise lfastened to the inward side of the door frame lar head 6, on the inside ofi the projection 3,

anda spring 7 surrounds the bolt between the dprojection 2 and this annular head/ 6', to

hol the bolt norniall in retracted position. At its outward en( the bolt is provided with a hook 8. This hook is passed through a slot in a latch-piece 10, which is coupled to' the bolt by means oi" the pin 9. This latchpiece has a forward rojection 11, which closes the opening of t e hook 8, thus forniving two'l separable jaws, by which the loop of the vestibule curtain is held in place, as indicated by the broken lines in Fig. 2. The latch-piece is also provided with a-lever 12, which projectsbackwardacross the bracket, and is ongitudinally concavedto inclose the spring and bolt. This lever is carried suiciently beyond the .projection 3 to permit it to be grasped, when 'opening the fastener by hand. ,y

At 13, the latch-piece is fulcrumed against the face ofthe rojection 2'on the bracket, and when the Patch-piece is turned on its pivot connection with the hook 8, this fulcrum 13 rides out on the face of the projection 2,- and forces the ivot-pin 9 and the hook outward against t e tensionl of spring 7. The jaws of the fastener are thus separated, as shown in the broken line positions ,thereof in Fig. 2, permitting the loo of the curtain to be inserted in or released rom the fastener.

-When the latch lever 1 2 is thrown back into normal position, the fastenerwill .be locked against openin under ordinary 4strains` on the curtain; gbut, should undue tensioiiyoccur'in the curtain, as when the cars become separated, the latch-piece will be o ened\aga'inst the tension of spring 7, there y automatically releasing the curtainlOO lgrlien in open position, the latch-piece is revented from turnin the bolt in the bracket by means of gui e lugs 14, formed at the outward edges of the' projection 2. The bracket is also referably provided with side walls between t e projections 2 and 3, which rise, as showiiat 15 in Fi 3, to meet the sides of the latch lever 12, t erebyiorming a complete inclosure for the s ring `and bolt when the fastener is in norma position.

Having-thus described the construction and. operation of my fastener, and without confining myself to the particular arrangement of parts, as herein described, what I claim as In invention and desire to secure by Letters atent isn I y 1. A vestibule curtain-fastener comprising a hook, a latch-piece coupled to the hook and adaptedto close the opening of the hook, and means for yieldingly holding the latchpiece in closed osition upon the hook.

2. A vestibu e curtainfastener comprising a bolt susceptible of longitudinal movement in a support, a hook at one end of the bolt, a

ioo

t latch-piece coupled to :the hooked :end of the v ,bolt and adapted to4 close the o ening of the hook, said latch-piece being. ulcrumed on fthe bolt adapted to slide `in the other guide Y Way, a coile sides t ereof, a bolt passing'freely the slpport to move the bolt outward when turne to open osition, and means for yieldingly holdin t e bolt in retracted position. 3. A vesti ule curtain-fastener comprising a sup ort having guideways at 'opposite y rough one of said guidevvays, a nut on one end of spring surroundingthe bolt'between said nut and the first uideway, a hook on' the projecting end of-.t e bolt, a, latchpiece coupled to the hooked end of the bolt and ada ted to close the op'enin ofthe hook,

said lato -piece bein fulcrume on the support to move the b o t outward When turned piece for operating the fastener by hand. 4. Avestibule. curtain-fastener comprising 'a bolt susceptible of longitudinal movement the su port to move the `bolt outward| when turne to open osition,.and means for yieldlingly holding t e bolt in retracted position, n testimony whereof I have ahXed my signature, -in presence of two witnesses.
